Example 2

Referring to fig. 1 to 4, as a further optimized solution of embodiment 1, in this embodiment, the protective film 8 includes a transparent PET layer 81 and an acrylic pressure sensitive adhesive layer 82 disposed above the transparent PET layer 81. Preferably, the adhesiveness of the acrylic pressure-sensitive adhesive layer 82 requires a weak adhesiveness and is not adhesive residue, so as to avoid subsequent influence on the adhesive application effect of the ink layer 7.

Further, a film tearing handle 83 is arranged on the transparent PET layer 81 to facilitate subsequent tearing of the protective film 8. More preferably, the surface coating of dyestripping handle 83 has the color coating, and dyestripping handle 83 is coated with the color coating and can play the foolproof effect to whether avoid the staff conveniently to look over protection film 8 when the inspection and leak and tear, it can adopt manual mode to tear the membrane, also can be through tearing the membrane after machine identification. In this embodiment, the colour of colour coating is red, and red colour coating is comparatively bright-coloured for whether tear film just can be seen at a glance, make things convenient for quality control personnel to inspect.

Further, the protective film 8 has a sickle shape, which can protect the side edge regions and the lower end regions of the bottom ink layer 7, and the low molecular weight siloxane (D4-D20) adheres to the surface of the protective film 8 during the releasing process, and cannot directly contact the ink layer 7 of the cover plate 5.
